An Employing a Multistage Fuzzy Architecture for Usability of Open Source Software

The Demand for Open Source Software (OSS) is increasing day by day. However, its end users still face challenges using such software. Therefore, this study is conducted to propose a fuzzy usability model to be an approach for evaluating the usability of the open source software. In order to propose such model, six common usability characteristics have been considered, namely: Learnability, understandability, attractiveness, operability, efficiency, and memorability. Some of these characteristics are related to the open source software's features (Learnability, usability, attractiveness, operability); and the rest are related to the end users. Finally, the Matalab Simulink software (Fuzzy Logic Toolbox) has been employed to simulate and to validate the proposed approach model.
